Report one bug of "\ref".

When I use \ref (or \eqref), I meet the following problem:

If I write "Figure" or "Equation" or "Table", etc., then use "C-c )", a "~" will be automatically add before \ref or \eqref, which becomes, for example,

        e.g.: As shown in Figure~\ref{fig:good} and Equation~\eqref{eq:good}. 

This is nice.  However, if I replace "Figure" with "Fig.", "Equation" as "Eq.", etc., then if use "C-c )", there is no space or "~" before it, which becomes:

        e.g.: As shown in Fig.\ref{fig:good} and Eq.\eqref{eq:good}. 
 
This doesn't make sense.  In fact, I think we still need the space or "~" as below:

        e.g.: As shown in Fig.~\ref{fig:good} and Eq.~\eqref{eq:good}. 

Furthermore, if I add a "~" manually after "Fig." as "Fig.~" and "Eq." as "Eq.~", it will automatically remove the "~" when I use "C-c )".  This feature is too much.  I think in most case, we need "~" between them because the dot "." here is not a period, but is used for abbreviation.

Is there any possible way to revise it?  Thanks.


BTW: I'm using AUCTeX 11.54
                         CVS Emacs 21.3
                         Windows XP.
